Forward error correction techniques suitable for the utilization in the PLC technology

Abstract

Todaypsilas PLC systems are mostly limited in transmission speeds to several kilobits per seconds. Such speeds are certainly not sufficient for running popular services like a broadband Internet, a teleworking or the Video on Demand. This fact is reducing a chance of the PLC technologypsilas deployment in a wide range. One way how to overcome this problem could be in introduction of optimal errors correcting techniques into the PLC technology. In this contribution, different types of coding techniques are discussed, including RS, Turbo or Convolutional codes. Theoretical analyses are focused on their positive and negative features visible in case of their deployment in the PLC transmission environment. Special attention is pointed to their robustness against noises, which is analyzed also practically in form of the simulations. Analyses and simulations are done for individual codes as well as combination of codes.
